What should be fixed is the "doube swap bug" where you can't swap because (i assume) both of you have swapped at the same time. i had a diamond 2 Quinn player (who i had ignored from a previous game) who pick her for Top and i assumed she was AD. As a result her duo and herself trolled my game by feeding 0-15 in 10 min even she could totally play botlane...

In the first matchmaking my team was perfect. Everyone had their place. But then someone in the other team leaves and the organisation I had in my previous team is gone...
Riot needs to fix that once your team is sorted out and someone leaves on the other team that your team still has to be the same..

When someone dodges, leave the queue for a minute or two, that way you can avoid getting the enemy team who had to dodge.
